Very rough figures for a typical terrace dormer could be 5x4x2-ish (divided by 2 cos only half of it is new space) so about 20 cubic meters. Extra room above the outrigger 3x3x2 or 18 cubic meters.
Doesn't leave much to play with.
Mine are quite offset too, about 3 or 4 steps in it so imagine the volume would really be pushing it.
